Maybe some can help fill in some history here (*note: the Corvette 'dropped' in power and Fed HP calculations changed during C3 years):

Outgoing Base Corvette.......'New' Base Corvette

C1>C2 (1963) 250HP................300HP
C2>C3 (1968) _____HP...........____HP
C3>C4 (1985) _____HP*...........300HP
C4>C5 (1997) 300HP................350HP +50
C5>C6 (2005) 350HP................400HP +50
C6>C7 (2014) 436HP................456HP +20

Gezz, what is it with you and this downer attitude about Corvette power?
It's gonna be what it's gonna be and people will mod it if they don't like it or they won't buy it.

ATC399

Its going to be a power too weight thing...However all we know for now is 450 minium...relax OP its going to be a Beast...Any true Vette Fan is going to want one..jmho...

vette6799

I don't get it. You need to know the weight before you can say anything about HP.

And if you want power, I suspect that when the big stuff comes out, no one will be disappointed. 638 is a fair amount of horsepower in a stock vehicle that doesn't weigh a heck of a lot.

c4gone

Hey op can u figure this out for tire pressure

AFVETTE

I suggest you buy a GT500 if HP numbers are so important to you.

AC04

At current HP levels in the base, it is plenty, you certainly want to see some gains but the law of diminishing returns apply. You can't expect the 15% you got from the C4-C5 IMHO. I am sure we will be pleased though there will be some haters.

BMadden

Where are you getting 456 from anyway?

bigterpsfan

Jeeze he was just asking a fair question. On another note, while my Z06 has been completely reliable (knock wood) I realize some have not. I hope other than minor quality issues they are all reliable as possible. As far as hp is concerned, there will be higher hp variants to come.

I expect it to exceed 45x hp fairly easily, if not, yeah sorry to say but gm dropped the ball. I don't care how many on here talk about 100lbs less and 450hp being great, it's still a tough sell.

That being said, last year c3 and first year c4 were identical engines. Also, technically there was the c4, c4 zr1, and in 96 the c4 had either lt1 or 330hp lt4 with no other changes anywhere in the car. And considering I've seen dyno charts of them hitting all but 300whp...

But based on your chart, yeah. With a more realistic 476hp, that's 46 or 40hp increase.

Starting in 1971 they started giving the horsepower as net where it was given as gross before.

1971-270hp

RobWilson

1972 was the first yet for net hp. Compression ratios were dropped in 1971, so that was an actual hp decrease.

VETTEMANN

Thanks. There are definitely some yahoos on here, dealers and connected to GM in other ways, who will post the C7 is great no matter what the reality. I do think the diminishing HP gains tell a story that the HP wars are coming to an end - just look around, mfgs are racing hybrids at LeMans

My concerns are two-fold:

1) GM shifting its commitment away from Corvette racing heritage - but 'fast talking' to shift our attention away from that (we'll just have to see how/if they support racing with this C7), and 2,

2) GMs recent suspect commitment to reliability - ignoring pleading concerns from the Z06 community, just to move on and sell some C7s...

With narrower tires, and Euro wannabe looks, I fear the C7 moves the Corvette away from being a car with a more pure sports car purpose, to a sporty techno-car designed to appeal more to the younger, 911/Lambo/R8 nightclub crowd. E.g. Like when everyone sees a Lambo - it turns heads - but then it looks totally out of place on a race track.

Newer is not always better.

But the biggest issue may be GM's commitment to reliability in Corvettes, as Z06 owners have recently experienced good reason to question that (see the C6 Z06 forum).

Five hours and forty minutes to go then we will all know!!

RC000E

These figures hardly represent the facts though. Peak hp numbers don't amount to ****, its the power curve prior to peak that makes a world of difference.

In my prior shop, despite my pleas with certain customers, they'd often chase peak hp figures that look nice on the internet, while losing substantial amounts of torque to obtain it. I've built cars with 150 more PEAK hp at the wheels, that went slower in the quarter mile. Transient response and how you get the given amount of power to ground is what counts. On top of the fact this doesn't even take into consideration power to weight.

Narrow minded, misleading and misinformed post...

BRISLS1

Thanks, 05DSOM! Great post, illustrating what diverse power numbers have been produced over the years. So maybe it is not a year by year incremental comparison.

Some folks don't want to mod the car. So raising the bar on the base Coupe each year, 350, 400, 436, 450, etc.. etc.. does excite the customer base. Great point made about percentage! It is easy to uncork the first 50 horses, maybe not so the next and next.

OT: Saw a cherry 2007 Z06 go "through" Carmax yesterday. Couldn't even refresh my browser. At 2000 miles on the clock that baby was gone.

goatts

Could be irrelevant. We will have to wait for the first track tests/comparisons. I think we've reached the limit for hp at 450 on base cars of any manufacturer.

Walford

Thanks for that.

I was pretty sure that the C2 carried over all the engines from 1962, maybe with a little tweaking, and the C3 carried over all the engines from 1967, maybe with a little tweaking. I know for a fact that the 1984 had the exact same "crapfire" engine that the 1982 had.

The LS1 was the first all-new Corvette engine to be put in an all-new Corvette in 1998.

So yeah, the 30-hp bump is less than the 45-hp bump in 1998 and the 50-hp bump in 2005, but at least they're giving it a bump. Three times before, the new Corvette didn't get a more powerful engine.
